Wall Boundary Conditons
 
Hi,

I've been running explicit compressible flow calculations using Jameson's central differencing scheme with combined 2nd/4th order smoothing. The calculations keep blowing up and I've observed that the instability always starts with some points adjacent to wall boundaries.

Need to know how to stabilize the calculations. Appreciate any advice on the matter.

Thanks in advance

Hello Mahesh,

Yes, using Jameson's combined 2nd/4th order with pressure switch.

Thanks Chan K I
